Chapter 24, Problem 24.14EP

(a)

Interpretation Introduction

Interpretation: To identify the step in which the $\text{2}-\text{phosphoglycerate}$ molecule is encountered as a reactant.

Concept introduction: Glycolysis is the metabolic pathway that breaks down a glucose molecule and converts it into two pyruvate molecules along with the production of two ATP molecules and NADH coenzymes.

The block diagram to represent an overview of glycolysis is as follows:

From the above diagram, it is concluded that in the overall process of glycolysis, two stages are present.

a) Steps 1 to 3 represents a six-carbon stage $\left({\text{C}}_6\text{ stage}\right)$.

b) Steps 4 to 10 represent a three-carbon stage $\left({\text{C}}_3\text{ stage}\right)$.

A reactant is defined as the substance that is initially present in the chemical reaction and gets consumed to form a new substance.

(b)

Interpretation Introduction

Interpretation: To identify the step in which the $\text{1,3}-\text{biphosphoglycerate}$ molecule is encountered as a reactant.

Concept introduction: Glycolysis is the metabolic pathway that breaks down a glucose molecule and converts it into two pyruvate molecules along with the production of two ATP molecules and NADH coenzymes.

The block diagram to represent an overview of glycolysis is as follows:

From the above diagram, it is concluded that in the overall process of glycolysis, two stages are present.

a) Steps 1 to 3 represents a six-carbon stage $\left({\text{C}}_6\text{ stage}\right)$.

b) Steps 4 to 10 represent a three-carbon stage $\left({\text{C}}_3\text{ stage}\right)$.

A reactant is defined as the substance that is initially present in the chemical reaction and gets consumed to form a new substance.
